title: The complete mitochondrial genome of Hyattella sinuosa (Dictyoceratida: Spongiidae).
abstract: The mitochondrial genome of Hyattella sinuosa (Dictyoceratida: Spongiidae) is a circular molecule of 16,422 bp in length, containing 14 protein-coding genes, 2 ribosomal RNA genes, 2 transfer RNA genes(trnW and trnM) and 13 non-coding segments. All genes are distributed in the same strand (H-strand). The overall base composition of the H-strand is as follows: T (37.72%), C (11.27%), A (25.14%), G (25.86%), with GC- and AT-skew of 0.393 and -0.2, respectively, reflecting unbalanced base composition between the two strands. The non-coding regions are 1240 bp in total length, with high-AT content (73.72%). The current mitochondrial genome is identical to that of Hippospongia Lachne (Family Spongiidae) in gene order and contents, except for the absence of the repeat hairpin-forming element (RHE) in the non-coding regions.
